Embodiment 1

[0035] Such as figure 1 , 2 As shown, in this embodiment, the semi-energy storage electromechanical brake includes a housing 9, a brake caliper body 4, a brake disc 1, and a friction plate 2, which can push the friction plate 2 forward to clamp the brake disc 1, and a gap self-adjusting mechanism 3 that can automatically adjust the braking gap between the moving mechanism and the friction plate 2.

[0036] The power mechanism includes a motor 11, an electromagnetic clutch 12, a torque amplification mechanism, a motion mechanism for converting the rotational motion of the motor 11 into a linear motion, and an elastic mechanism.

[0037] In this embodiment, the torque amplification mechanism adopts a reduction mechanism 8, and the reduction mechanism 8 includes a pinion gear set on the output shaft of the motor 11, an intermediate gear meshing with the pinion gear, and an output gear meshing with the intermediate gear . The output gear is fixed on the input end of the motion ...

Embodiment 2

[0057] The difference between this embodiment and Embodiment 1 is that this embodiment does not have the gap self-adjusting mechanism 3 in Embodiment 1. Wherein, the front end of the lead screw 7 can directly contact the friction plate 2, and the brake can be realized by eliminating the gap between the brake disc 1 and the friction plate 2.

[0058] Other structures and uses in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0060] The difference between this embodiment and Embodiment 1 is that this embodiment does not have the elastic mechanism in Embodiment 1.

[0061] Other structures and uses in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a semi energy storage type electromechanical brake which comprises a shell, a brake disc, a friction plate and an actuating unit capable of pushing the friction plate to move forward so as to clamp the brake disc. The actuating unit comprises a motor and a moving mechanism connected with the output end of the motor; the moving mechanism can convert the rotational motion of the motor into linear motion; the actuating unit further comprises an elastic mechanism which is sleeved on the moving mechanism and props up against the inner wall of the shell in a compressed state; and when the moving mechanism moves linearly forward, the elastic potential energy of the elastic mechanism is released to push the moving mechanism to accelerate forward. Correspondingly, the invention provides an automobile comprising the brake. The brake can generate braking clamping force through the coupling output torque of the elastic mechanism and the motor, so braking through a big braking clamping force when the output power of the motor is small is realized, the response time of the braking system is shortened, the output power of the motor is reduced and the braking effect is good.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a semi-energy-storage electromechanical brake and an automobile comprising the semi-energy-storage electromechanical brake. Background technique [0002] With the development of automobile technology, people have put forward higher requirements for the power, economy, safety, maneuverability and comfort of automobiles, and more efficient and energy-saving electromechanical braking systems have emerged. Mechanical systems in automobiles There is a gradual transition to electromechanical systems. [0003] The electromechanical braking system uses electronic components to replace some mechanical components, and replaces all the brake pipelines with wires, which saves a lot of valve components in the braking system, shortens the braking response time, improves the braking performance, and saves In addition, the electronic control unit ECU is used for the...
