The friction plate of the dry shoe brake is easy to wear and has poor use reliability; the oil bath disc brake has a complex structure and is inconvenient to maintain; and the two types of brakes are mechanically transmitted to generate braking force, so that the brakes are not well arranged on the design of the whole structure, and the optimal design of the whole structure is affected.
In addition, the wet, disc, hydrostatic steering brake used on the high horsepower tractor 200 has a complex structure, requires high machining and assembly costs, and is not easy to use in hilly and mountainous areas, particularly mountainous areas.

Since the power pump 105 has two pump oil chambers, the two pump oil chambers are connected to the first and second brake plates 1072 and 1075, respectively, in one-to-one correspondence. The first braking plate 1072 and the second braking plate 1075 are rotatably connected to the chassis 21 through a pedal shaft 1077, the first braking plate 1072 controls the pump chamber corresponding to the first braking plate, and the second braking plate 1075 controls the other pump chamber corresponding to the second braking plate.
When simultaneous braking is required, the first and second brake plates 1072 and 1075 are connected by the pedal shaft 1077 so that the first and second brake plates 1072 and 1075 can simultaneously rotate around the chassis 21 to control the on of the power pump 105.
Specifically, the first brake plate 1072 includes a first linkage portion, a penetrating hole is formed in the first linkage portion, the second brake plate 1075 includes a second linkage portion, a penetrating hole is formed in the second linkage portion, the penetrating hole of the first linkage portion corresponds to the penetrating hole of the second linkage portion, and the penetrating hole of the first linkage portion and the penetrating hole of the second linkage portion are sequentially penetrated through the pedal shaft 1077, so that the first brake plate 1072 and the second brake plate 1075 are fixedly connected, and only one pedal is needed to brake simultaneously.

The number of the hydraulic transmission mechanisms 14 is two, the input end of one hydraulic transmission mechanism 14 is connected with one pump oil port of the power pump 105, and the output end is connected with the braking mechanism 18 of one driving wheel 22; the input end of the other hydraulic transmission 14 is connected to the other pump port of the power pump 105, and the output end is connected to the brake mechanism 18 of the other driving wheel 22.
Each hydraulic transmission mechanism 14 comprises a brake oil pipe 142, a brake booster 15, a first brake branch pipe 162 and a second brake branch pipe 165, wherein the brake oil pipe 142 is located between the power pump 105 and the brake booster 15, in this embodiment, the brake booster 15 has one inlet and two outlets, one end of the brake oil pipe 142 is connected with the pump oil port of the power pump 105, the other end is connected with the inlet of the brake booster 15, and the first brake branch pipe 162 and the second brake branch pipe 165 are respectively connected with the output end of the brake booster 15.
I.e. one end of the first brake branch 162 is connected to one of the outlets of the brake booster 15, the other end is connected to a first brake 185 of the brake mechanism 18, one end of the second brake branch 165 is connected to the other outlet of the brake booster 15, and the other end is connected to a second brake 188 of the brake mechanism 18.
The brake booster 15 in the present embodiment is a hydrostatic brake booster, and since the hydrostatic brake booster boosts the hydraulic oil output from the power pump 105 by the hydraulic booster, the boosted hydraulic oil is used to operate the wheel cylinders by the master cylinder, so that the operation is easy during braking, and the braking is reliable.
The manufacturing cost of the hydrostatic brake booster is only one tenth of that of a vacuum booster system. When the brake pad 107 is lightly applied, the output pressure of the hydrostatic brake booster 15 is almost twice the input pressure, and the braking effect can almost achieve the effect of vacuum boosting.
The boosting principle of the hydrostatic braking booster is as follows: in the initial stage of braking, when large-displacement brake fluid is needed, the booster does not work, and after the brake plate 107 contacts the brake drum and generates certain pre-pressure, the booster starts the booster valve, and the displacement of a small part of the main cylinder is sacrificed, so that the effect of increasing the braking pressure is achieved. Therefore, although the output pressure is increased, the increased displacement of the main cylinder is very small, and the requirement of the displacement after the booster is installed is completely met by adopting the braking main pump.

The first brake 185 and the second brake 188 are simultaneously connected in a transmission manner through the hydraulic transmission mechanism 14, and the first brake 185 and the second brake 188 are respectively matched with the brake disc 182 through the hydraulic transmission mechanism 14, so that the braking performance is enhanced.
In this embodiment, a set of braking mechanisms 18 is disposed on each driving wheel 22, and the braking mechanisms 18 and the hydraulic transmission mechanisms 14 form execution assemblies, the number of the execution assemblies is two, and the two execution assemblies are respectively connected with the output ends of the power assembly 10.
The working principle of the tractor brake system 100 provided in this embodiment is that, during operation, an operator pushes the power pump 105 by stepping on the brake plate 107, so that the power is boosted by the brake booster 15 of the hydraulic transmission mechanism 14 and then transmitted to the first brake 185 and the second brake 188.
