===Introduction===

Sprockets and chains provide a cost effective way of reducing the speed of rotation of the motor to the speed required by the driven axle.
[[File:Sprocket overview.jpg|thumb|400x400px|Sprocket|none]]

===Chain types===

The are many different types of chain and they have to be matched to the sprocket

Common types in this application are T8F , #25

Going too large in the chain size (distance between links) will limit the maximum number of teeth for the sprocket on the axle (it will be dragging on the ground!).

Going too small in the chain size will limit the size of the teeth and therefore the strength of them. This means they can wear out quickly.

===Sizing your sprockets===

The max speed of a Hacky is usually 25 Miles per hour. This is largely due to the trade off between torque / top speed / track length. With the limited power budget (30A) it limits the motor current and therefore the available torque. Corners come regularly in a Hacky race so a high top speed is often less important than good drive out of corners

So lets work the numbers out -

25 Mph = 1.60934*25 = 40.2 Kph

40.2 Kph = 40.2 * 1000 / (60 * 60) = 11.18 metres per second

Now we need to factor in the tyre diameter

Lets take a mid-sized tyre 310 mm

=310*3.142/1000 = 0.974 m

Now we have this we can calculate the rotations per second the wheel has to make

= 11.18 / 0.974 = 11.48 rotations per second

Motors have a speed range and if you are using a MY1020 2000W brushless motor then they have a speed range where their peak performance is around 4300RPM.

This will vary and its best to check the motor specs although these are usually not well documented from the typical Chinese suppliers.

4300 RPM = 71.66 rotations per second

The motor are usually supplied with an 11 tooth sprocket but different ones from 9 – 13 teeth are readily available (Note: if it’s a MY1020 motor the retaining nut is left hand thread)

So what is the size of the larger sprocket? Well you have done the hard work now

= (71.66 / 11.48) * 11 = 68.66

Larger T8F sprockets are readily available – search Ali for “T8F Chain Rear Sprocket 38 44 54 58 64 74 Tooth”

You can also search for plate sprockets.

Going for a slightly smaller sprocket on the motor e.g. 9 teeth would give a theoretical 56 tooth on the axle , therefore 54 or 58 would be a decent compromise

===Chain Length Calculation===

===Chain adjustment===

All chains stretch and you need to have adjustment. This is usually easiest accommodated in the motor mounts rather than the axle.

Keep enough tension so that the chain doesn’t come off but not so that its fully under-tension all the way round. Its worth checking this by rotating the wheel 90 degrees (4 times) and check the chain tension as things are never perfectly round.

===Chain alignment===

This is critical. If you are used to Shimano style sprockets on a bicycle then they work by using chain mis-alignment to move up and down the sprockets. If you don’t get the alignment of the sprockets correct then you run the risk of the chain coming off the sprockets. Check both the alignment to each other and the axle

===Chain lubrication===

If chains are not lubricated they can rust and the links start sticking. On the other hand Hackys tend to race in lightly mowed fields so get exposed to dust and dirt. Use a thin lubricant like WD40 and apply more frequenly

Event Venue Requirements

2025-03-20T20:29:25Z

Shakesc:

==Venue Requirements==
Venue requirements typically are related to :-

* Space - circuit size sufficient for the number of hacky participants including safety barriers, pits to service the hackys, telemetry and PA.
* Power - we are electric powered so the ability to charge and power equipment keeps us rolling.
* Storage - for multi-day events secure storage is helpful.
* Access - access to race area to load/unload is great, we have a surprising amount of equipment.
* Visibility - we love to entertain so space for spectators is always great.
*

==Circuit Requirements==

===Track Surface===
Hacky Racers typically run on grass/dirt although hard surfaces such as tarmac is an option. A level of unevenness in the surface is expected though Hackys ground clearance , circa 100mm with wheels in the order of 300mm, limits length of grass and roughness. Hosts should understand that grass will get torn up over the course of events.

===Size===
Typically 20m*40m is the absolute minimum to race. Having double that in both directions is perfect. This equates to a lap time of around 10 – 15 seconds. This area contains the circuit, pits made up of four 4.5m x 4.5m tents, timing station and spectator exclusion zone. Tracks larger than 50m*100m are possible for 20+ entries, but typically too large/slow for smaller events. [make a diagram]

===Pits===
Pits need to be covered if outdoors. We can bring up to four of 4.5*4.5m pit tents which is typically adequate for 10-15 entries. Larger events will require additional pits area. Ideally plan for 2*4m-4*4m per entry.

===Safety Barriers===
In lieu of payment, we usually ask that host events provide the track and crowd barriers free of charge. If budget is tight, we can provide barriers for soft surfaces.

The track must be marked by (in order of preference):
#Large plastic traffic barriers
#Straw bales
#Curbs
#Plastic totes (Hacky Racers can provide these)
#Cones

Public events with spectators also need a crowd barrier set 2m back from the track. This can be:
#Metal crowd barriers
#Net and fence pins (on soft ground)
#Straw bales
#A single line of hazard tape is minimum but may only be used on low traffic areas (e.g. around pits), as children will dip under and get on track if used as a primary crowd barrier around the track.

On hard surfaces, either the track barrier or crowd barrier need to be fairly weighty to arrest out of control karts. On soft surfaces, the net and fence pins are the bare minimum.

We have previously been able to loan straw bales from a local farm.

===Infrastructure requirements===
====Electrical====
For a general event of up to 10 entries, we can run off a pair of 13A sockets (6kW). One socket (3kW) is possible for small events, but can cause nusiance tripping and having two is both safer and provides redundancy. Ideally plan for 500W-1kW per entry. 16A commando/ceeform sockets can be used if adapters are arranged in advance. The electricity supply should be RCD protected, located in the vicinity of the pits, and weatherproof if outdoors.

1 13A socket is also required for the timing system on the track, but it is typically located next to the pits and can run from an extension lead.

We have lighting for night racing if that is required.

====Vehicular access====
Ideally there is access to the Hacky track via car/van to unload and load. Parking after can be remote.

===Safety and Marshals===
Hacky Racers are a Motorsport UK affiliated group. We therefore have public liability insurance and comply with Motorsport UK code of conduct, as well as our own rules. We run events with safety marshals and operate yellow and red warning flags. The Hackys have a technical check before competing, along with drivers and marshals briefings.
The technical specifications are published on our website.

We will bring basic first aid materials, and suitable fire extinguishers. We ask that host events provide professional medical first responders, though it's not essential. Similarly, we will manage the crowd using the barriers and PA, but we may call on the host events for support if the crowd gets dangerous or disruptive.

===Circuit Example===

====Public Event====
This is an example of the circuit at EMF Camp (held at Eastnor Castle).
Here the tote boxes are being used along with plastic netting for spectator safety exclusion zone. The telemetry rig for timing can be seen suspended across the track.

====Private Event====
This is an example of the circuit at FootFest.
This is a smaller private event, but the aerial photo shows a typical layout of the track, pits and timing gantry.

== Background ==
[[File:Bricks hero shot small.jpeg|left|thumb]]
Theme is to look like Lego blocks. It uses baking trays sprayed in various bright coloured car paints

It builds on the learnings of Jeepney, LEtsGO and LEtsGO2, trying to resolve some of the issues that they had

See more of the build log on https://www.facebook.com/JacklsRobots<nowiki/>{{clear}}

== Construction ==
How is the chassis constructed?

Majority of the chassis is constructed from 20mm x 20mm box section. Its fully welded together

The box section used allows a level of flex over rough surfaces that is beneficial
{| style="margin: 0 auto;"
|[[File:L2_chassis.jpg|alt=Brake Disc|thumb]]
|}
Steering? Geometry?

Steering is direct in the style of a go-kart

There is about 8 degrees of negative camber and around 8 degrees of positive caster

Where are your wheels, tyres, hubs, axles from?

Majority of components are from mini ATVs

It uses tyres13x5.00-6 with a knobbly pattern.

The axle is a cutdown single axle from an ATV. This has been cut in half and turned down.

The hubs are bored out and welded onto the shaft. No chance of moving around

How do your brakes work?

Each axle has a brake disc with a hydraulic braking system using components from an ATV

The master brake cylinder is actuated directly from the brake pedal
{| style="margin: 0 auto;"

|}
{{clear}}

== Powertrain ==
Motor

Uses twin 1500W BLDC motors. The chain tension can be simply adjusted by slacking a couple of easy access bolts.

ESC

2 x Whitebox 1500W e-bike controller. These are not modified as the Hacky runs close to the fuse limit with 3Ah consumed per race

It has been run on 2 x 2000W controllers with a 40A fuse. It was a blast but not race legal.

Details of chain and gear ratio?

11: 64 sprockets through a chain

Do you have a diff?

No diff fitted, the dual motors act as an electronic diff.
There is a software diff based on a number of monitored sensors.

Where is your battery from?

It builds on the original Jeepney and LEtsGO, trying to resolve some of the issues that they had

See more of the build log on https://www.facebook.com/JacklsRobots<nowiki/>{{clear}}

== Construction ==
How is the chassis constructed?

Majority of the chassis is constructed from 20mm x 20mm box section. Its fully welded together

The box section used allows a level of flex over rough surfaces that is beneficial

|[[File:L2_chassis.jpg|alt=Brake Disc|thumb]]
|}
Steering? Geometry?

Steering is direct in the style of a go-kart

There is about 8 degrees of negative camber and around 8 degrees of positive caster

Where are your wheels, tyres, hubs, axles from?

Majority of components are from mini ATVs

It uses tyres13x5.00-6 with a knobbly pattern.

The axle is a cutdown single axle from an ATV. This has been cut in half and turned down.

The hubs are bored out and welded onto the shaft. No chance of moving around

How do your brakes work?

Each axle has a brake disc with a hydraulic braking system using components from an ATV

The master brake cylinder is actuated directly from the brake pedal

== Powertrain ==
Motor

Uses twin 1500W BLDC motors. The chain tension can be simply adjusted by slacking a couple of easy access bolts.

ESC

2 x Whitebox 1500W e-bike controller. These are not modified as the Hacky runs close to the fuse limit with 3Ah consumed per race

It has been run on 2 x 2000W controllers with a 40A fuse. It was a blast but not race legal.

Details of chain and gear ratio?

11: 64 sprockets through a chain

Do you have a diff?

No diff fitted, the dual motors act as an electronic diff.

Where is your battery from?

Hobbyking but now consistently out of stock{{clear}}

== Other Features ==
[[File:Placeholder.jpg|right|thumb]]
Changing the wheel/tyre changes the ratio of the gearing by a few percent which can be handy{{clear}}
