Abstract

The invention is composed of engine, stepless transmission, stepped transmission, differential, steering gear, transmission box, lifter, lumped brake, tripod, frame, circuit, oil circuit, solenoid valve and sensor, etc., and is a A non-memory, non-angle, instantaneous, and linear power steering system that can steer without displacement, avoiding the memory and nonlinearity of mechanical steering in angle and trajectory, and saving a lot of computing costs for intelligent driving. The solenoid valve directly controls the steering gear , CVT, brakes and lifters, etc., are beneficial to remote control, automatic driving, assisted driving and network driving, and gain advantages in maintenance, safety, operation and car popularization; this system has four-wheel drive and eight-wheel drive, four-wheel drive The four-wheel drive is mainly equipped with cars, and the eight-wheel drive is mainly equipped with harvesters; such a harvester does not require car transportation, which is conducive to passing extreme roads, the cab is not super high, and there is also intelligent driving when driving, which saves a truck for practitioners increase people's willingness to buy a machine.

Description

technical field

[0001] The wheel center steering system is a non-angle, non-memory, instantaneous and linear power steering mechanism, mainly used in harvesters and smart cars, related to the field of driverless cars, involving a dual-flow transmission. Background technique

[0002] 1. The center steering originated from the Second World War. It was first used in tanks and was famous all over the world for turning around in place. Due to the material strength and manufacturing limitations at that time, coupled with the huge destructive power of the war, the failure rate of center steering tanks was very high; After the war, the use of center steering was still tanks, and civilian use was very rare. During World War II, the road traffic in various countries was very underdeveloped, and tanks had strong off-road capabilities. The center steering system is a compromise between off-road and high mobility. The current application range is almost zero, but the market demand is gr...

Embodiment Construction

[0059] specific implementation plan

[0060] 1. The wheel center steering system is powered by a diesel or gasoline engine 1-1, the main transmission 1-2 drives the auxiliary transmission 1-3, and the torque of the differential 1-4 is distributed to the second tripod 1-22 and the tripod Three 1-23 and universal joint 1-6, universal joint 1-7 drive transmission 1-11 and transmission 1-13, the transmission drives the tripod one 1-21 behind, lumped brake 1-12 It can be parked or used as a service brake. The hydraulic oil pipe 1-8 is connected to the engine 1-1 and the steering gear 1-5. The first container 1-9, the second container 1-10 and the third container 1-14 can hold fuel, Water and hydraulic oil, triangular box 1-15, supporting wheels 1-16, reinforced triangle 1-17, tripod shaft 1-19 and supporting wheels 2-20 form a tripod, and lifter 1-18 specifically damps and Chassis lifting function.

[0061] 2. The wheel-type center steering system has two types: four-wheel drive ...
