Description
Technical Field
The utility model relates to a CBS linkage brake system, concretely relates to hydraulic pressure distributing valve for CBS linkage brake system.
Background
The braking system is the most critical active safety device for ensuring the safe running of the motorcycle, so the basic requirements of the braking system of the motorcycle are as follows: no matter the motorcycle is under any speed, load, high or low adhesion wash surface and weather conditions, the freckle driver can realize the stable and rapid deceleration of the motorcycle through simple operation in the braking process until the motorcycle stops.
Most of the existing two-wheeled motorcycles adopt a front wheel and rear wheel independent braking system, and during the braking process of the motorcycle equipped with the braking system, the operation force of hands and feet can be reasonably distributed to obtain reasonable deceleration, so that the front wheel and the rear wheel fully utilize the adhesion coefficient of the road surface.
Under the premise of not changing the front and rear brake structures of the original vehicle and maximally reducing the cost, the front and rear wheels can be synchronously and jointly braked during braking, and the technical problem to be solved by technical personnel in the field is solved.
In view of this, a CBS linkage brake system appears in the market, and the principle of the CBS linkage brake system is that a hydraulic distribution valve is used to connect a front brake system and a rear brake system respectively, and the front brake system and the rear brake system are linked to brake at the same time, but the existing CBS linkage brake pump is unreasonable in structure, so that the processing is very troublesome.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
a hydraulic distribution valve for a CBS linked brake system is provided.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a hydraulic pressure distributing valve for CBS linkage brake system, including the valve body, its characterized in that: the middle part of the valve body is provided with a plunger installation cavity with an opening at one end, a plugging piece is installed at the opening part, a plunger assembly capable of reciprocating along the plunger installation cavity is installed in the plunger installation cavity, the plunger assembly comprises a plunger and a return spring with one end abutting against the plunger and the other end abutting against the plugging piece, the other end of the valve body, opposite to the opening of the plunger installation cavity, is provided with a first oil duct which is vertically arranged with the plunger installation cavity, the plunger installation cavity is communicated with the first oil duct through a first oil duct communication hole with the outer diameter smaller than that of the plunger installation cavity, the first oil duct is provided with a first oil pipe joint for connecting a rear wheel brake master pump, one side of the valve body is provided with a second oil pipe joint for connecting a rear wheel brake slave pump at the other end of the first oil duct opposite to the first oil duct, the valve body is provided with a second oil duct which is arranged at intervals with the first oil duct at the same side of the first oil duct, the second oil duct is equipped with the third oil pipe joint that supplies the front wheel brake master cylinder to connect at first oil pipe joint homonymy, and the other end is equipped with the fourth oil pipe joint that supplies the front wheel brake wheel cylinder to connect, is equipped with first sealing, second sealing and the installation department that sets up with the second sealing interval in proper order on the plunger, first sealing external diameter is greater than first oil duct intercommunicating pore internal diameter, second sealing external diameter and plunger installation cavity internal diameter looks adaptation, be provided with first one-way seal assembly between first oil duct intercommunicating pore and the first sealing, be equipped with the one-way seal assembly of second between second sealing and the installation department, return spring butt in the installation department and make first one-way seal assembly offset with first oil duct intercommunicating pore.
