Abstract

A fourth wheel brake double circuit hydraulic brake apparatus, manual main pump (2) connects with the end of first four-way junction (3) via oil pipe (13), One of the output ends of the first four-way junction (3) connects with back wheel (6) via oil pipe (16), and the another tow output ends separately connects with the front left, right sub pumps (4,5) via oil pipe (14,15); foot brake master pump (8) connects with the input end of the second four-way junction (7) via oil pipe (20), One of the output end of the second four-way junction (7) connects with back wheel sub pump (6) via oil pipe (17), Anther tow output ends connects with the front left, right sub pumps (4,5) via oil pipe (18,19). The invention can realize front back wheel isochronous coordinate brake, When one of the hand brake master cylinder and the foot master cylinder is out-of-order, The brake function will not be effected, It is homologous to possess double insurance function. So, it is in high assurance coefficient.

Description

technical field [0001] The invention relates to a braking device, in particular to a four-wheel braking device for beach vehicles. Background technique [0002] Currently, the braking of the front and rear wheels of a quad bike is performed independently. The front wheel can be braked by holding the brake handle on the handlebar, and the rear wheel can be braked by stepping on the foot brake pedal. This braking method has potential safety hazards in actual driving. If an emergency occurs during driving, the driver immediately steps on the foot brake pedal to brake the rear wheels, and at the same time holds the brake handle on the handlebar to brake the front wheels. At this time, the driver's hands must brake and hold the handlebar firmly. The operation is cumbersome and laborious, and it is difficult to achieve synchronous and coordinated braking of the front and rear wheels when using both hands and feet. It is more likely to cause safety accidents when there are heavy ...
