Embodiment Construction

[0025] In order to overcome the problems of untimely braking and mitigation response, instability and potential safety hazards existing in the existing double-sided brake joist structure type vehicle reducer actuator, this embodiment provides a figure 1 In the double-sided flat-push braking type vehicle reducer actuator shown, except for the oil cylinder, the left and right parts are all symmetrical to the center of the basic line, mainly including a plurality of parallel joists 1, and the top surface of the left and right ends of each joist 1 Each installs a basic rail 2,3 parallel to each other, and the inner and outer sides of the two basic rails 2,3 are provided with inner brake rail seats 4,5 and outer brake rail seats 6,7, and the inner brake rails The top surfaces of seats 4, 5 and outer brake rail seats 6, 7 are respectively provided with an inner brake rail 8, 9 and an outer brake rail 10, 11, on the joist 1 between the two basic rails 2, 3 A double-acting oil cylinde...

Abstract

The invention provides a double-surface, flat push and braking type executing mechanism of a speed reducer of a vehicle. An inner braking rail seat and an outer braking rail seat are directly and fixedly connected with a cylinder body and an oil cylinder piston part of a double-function oil cylinder, and other middle connecting pieces are not required, so that the transfer of the power and the stability are ensured, and at the same time, the outer braking seat is limited by the matching between a guide groove and a guide step of a supporting beam to only move in a horizontal direction, a transition column body is controlled by a swing rod through an axial movement pair to generate the rotation relative to an outer supporting seat through a rotary movement pair, and thereby, the movement amount generated by the swing of the swing rod in the low and the high directions is eliminated, the outer supporting seat is driven by the swing of the swing rod to move in the horizontal direction, and the problem that the braking or the release is not steady because of the high and low movement amount of the outer braking seat in the vertical direction in the prior art is solved. The double-surface, flat push and braking type executing mechanism of the speed reducer of the vehicle has the advantages of centering and reliable mounting, short braking and releasing time, compact structure, stable and reliable working position, and convenient maintenance.

Description

technical field [0001] The invention relates to an actuator of a double-sided horizontal push brake type vehicle speed reducer. Background technique [0002] At present, the vehicle reducer actuators used in hump marshalling yards in China have two structures, clamped and non-clamped, according to the braking principle. speed. It meets the operating requirements of the vehicle speed control equipment in the hump marshalling yard, improves the dismantling and marshalling capacity of the hump marshalling yard, reduces the labor intensity of operators, improves personal safety, and has significant social and economic benefits for railway freight. [0003] There are many types of non-clamp reducers. The reducer with electromagnetic energy and other braking has high energy consumption and high equipment cost during operation; the unit braking energy of the reducer with unilateral braking is small, and as the tonnage of the vehicle increases, the braking capacity needs to be fur...
