Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0039] like Figure 1-3 As shown, the present invention provides a parking brake for an automatic transmission, a parking brake for an automatic transmission, comprising: an inscribed ratchet 100 fixedly connected to the output shaft of the transmission, which is in the shape of an annular disc, and the inner The inner ring of the ratchet 100 is provided with multiple pairs of ratchet teeth in the circumferential direction, and each pair of ratchet teeth includes two radially opposite ratchet teeth 111 and ratchet teeth 112. Centrosymmetric. The first group of electromagnetic actuators includes electromagnetic actuators 210 and electromagnetic actuators 220, the second group of electromagnetic actuators includes electromagnetic actuators 230 and electromagnetic actuators 240...

Abstract

The invention discloses an automatic parking brake used for a transmission. The automatic parking brake used for the transmission comprises an interconnected ratchet; the interconnected ratchet is inan annular disk shape and a plurality of ratchet teeth are arranged at an inner ring of the interconnected ratchet along the circumferential direction; a first group of electromagnetic execution mechanisms comprise two electromagnetic execution mechanisms arranged opposite to each other along the radial direction of the interconnected ratchet and the electromagnetic execution mechanisms are mounted on a transmission shell body; the ends, which are close to the interconnected ratchet, of the electromagnetic execution mechanisms are fixedly connected with parking pawls; the structure of a secondgroup of electromagnetic execution mechanisms is the same with the first group of electromagnetic execution mechanisms; wherein, the parking pawls of the first group of electromagnetic execution mechanisms and the second group of electromagnetic execution mechanisms are capable of getting into or getting out from the interconnected ratchet; when the two parking pawls of the first group of electromagnetic execution mechanisms correspond to the positions of the ratchet teeth, the two parking pawls of the second group of electromagnetic execution mechanism correspond to the positions of the bottoms of the ratchet teeth. The automatic parking brake used for the transmission provided by the invention is simple in structure, smaller in occupied space and capable of improving parking success rate.

Description

technical field [0001] The invention belongs to the technical field of automobile parking brakes, in particular to a parking brake for an automatic transmission and a control method thereof. Background technique [0002] In today's society, cars have become an indispensable means of transportation in people's lives. With the development of science and technology and the improvement of people's living standards, people have higher and higher requirements for cars. Cars are no longer just ordinary means of transportation, but have risen to become a culture and a symbol. The importance of cars is self-evident. Metaphor. Therefore, the safety performance of automobiles has also been paid more and more attention. [0003] The parking brake, usually refers to the manual brake installed on the motor vehicle, which is used to stabilize the vehicle after the vehicle stops. If the parking brake effect is not good, the vehicle may slide when the vehicle is parked on an inclined road,...
