Problems solved by technology

Such as EMB, EHB, etc., but the EMB system uses a large number of electronic devices, so the backup when the brake fails is too complicated and the cost is too high; the number of solenoid valves used in EHB is too many, and the hydraulic pipeline is too cumbersome, making the system too complicated

Embodiment Construction

[0023] A multifunctional braking system with deceleration and torque increasing motion conversion mechanism and active adjustment of the present invention will be described below in conjunction with the accompanying drawings and specific embodiments:

[0024] Such as figure 1As shown, a multifunctional braking system with a deceleration, increasing torsion, motion conversion mechanism and active adjustment includes a brake housing 21, a motor 2, a brake pedal simulator, a brake master cylinder 3, a motion conversion mechanism, a hydraulic source, Solenoid valve and brake wheel cylinder 23. The brake pedal simulator is connected with the front section of the brake outer shell 21, and it is used to simulate the braking feeling and obtain the driver's braking intention, and is used to realize wheel braking when the motor 2 fails. The brake housing 21 is cylindrical, and its rear section is connected with the motion conversion mechanism. The motor 2 is installed on the brake mas...

Abstract

The invention belongs to the technical field of motor vehicle braking, particularly relates to a multi-functional braking system with declaration torque rising motion conversion mechanism and active adjusting. The purpose of the multi-functional braking system is to supply a system with compact structure, convenient arrangement and simple structure. The multi-functional braking system is characterized by further comprising a brake out shell (21), a brake pedal simulator, a brake master cylinder (3) and a conversion mechanism. By the multi-functional braking system with declaration torque rising motion conversion mechanism and active adjusting, a vacuum booster is canceled, the mechanical connection between the brake pedal and a liquid chamber is canceled, the total body mass is effectively reduced. The structure is compact and the arrangement is easy. The complexity in structure is highly decreased and cost is decreased. By using an electrical machine as the power source, that is connecting machinery with electric, the signal transmission is quick and braking response is quick. By adopting braking backups of mechanical structure, backup structure is allowed to intervene quickly to generate certain braking effect when electrical structure loses effect, and thereby driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle braking, and in particular relates to a multifunctional braking system with a decelerating and increasing torsion motion conversion mechanism and active adjustment. Background technique [0002] When a traditional car brakes, the driver usually steps on the brake pedal, and with the help of a series of mechanical structures and a vacuum booster, the oil in the brake master cylinder flows into each wheel cylinder through the brake pipeline at a certain pressure. , and finally drive the disc or drum brake to complete the braking action, so as to achieve wheel braking. However, with the increase of high-grade highways and the increase of the average speed of automobiles, coupled with the increase in the number of automobiles, in order to improve the driving safety of automobiles, domestic and foreign related enterprises and scientific research institutions have developed a series of active syst...
