Problems solved by technology
[0002] Most of the hand brake devices commonly used in existing automobiles use a mechanical lever to drive the cable to drive the piston of the rear brake cylinder cylinder to generate parking force. Due to the limitation of the size of the mechanical lever or the insufficient force exerted by the operator, the braking force generated by it is limited. Smaller, the parking force often cannot meet the safety inspection requirements and cause safety hazards

The hydraulic type vehicle hand brake booster of the present invention comprises a cylindrical shell fixedly arranged between the front end cover and the rear end cover, and a reset spring is built in the end of the cylindrical shell close to the front end cover; The oil cylinder block is fixedly arranged on the frame. One end of the oil cylinder body is provided with a large oil cylinder, and the other end is provided with a small oil cylinder. The large oil cylinder is provided with a corresponding large piston, and the small oil cylinder is provided with a corresponding small piston. The large oil cylinder communicates with the small oil cylinder; the oil cylinder is fixed There are several front tie rods and rear tie rods evenly distributed in a circle from the outside to the inside of the frame respectively. The two ends of the front tie rods are provided with corresponding front tie rod connection plates and the front tie rod connection plates are fixed on the front tie rod connection plate near the front end cover. , the two ends of the rear tie rods are provided with corresponding rear tie rod connection plates and the rear tie rod connection plates are fixedly arranged on the rear tie rod connection plate near the rear end cover side, and the corresponding front tie rod connection plates and rear tie rod connection plates are arranged alternately. The invention has simple structure and convenient operation.
Description
technical field [0001] The invention relates to an automobile brake device, in particular to a hydraulic type automobile hand brake force enhancer. Background technique [0002] Most of the hand brake devices commonly used in existing automobiles use a mechanical lever to drive the cable to drive the piston of the rear brake cylinder cylinder to generate parking force. Due to the limitation of the size of the mechanical lever or the insufficient force exerted by the operator, the braking force generated by it is limited. Smaller, the parking force often cannot meet the safety inspection requirements and cause potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic vehicle hand brake booster with simple structure, stable braking, safety and reliability, and long service life. [0004] In order to solve the above technical problems, the hydraulic vehicle hand brake booster of the present invention includes ...
