Abstract

The utility model discloses a hand braking clamp structure. Two movable friction plates are symmetrically arranged between two main clamp bodies; a brake disc is arranged in a gap between the friction plates; a cavity which is used for accommodating a piston mechanism is formed inside one of the main clamp bodies; a push rod piston and a propelling thread sleeve are mounted inside the cavity and form a thread pair; a pull locking rocker arm is fixed with the propelling thread sleeve through a spline and a rocker arm locking nut; one end of the push rod piston is exactly inserted into the spline of a gap adjusting plate; the pull locking rocker arm is connected with a pull locking bracket through a return spring; the push rod piston can move only along the self axis; by pulling the pull locking rocker arm, the push rod piston can be driven to move toward the friction plate, so that parking and hand-braking functions are realized; the pull locking rocker arm is loosened and returns to an original position under the action of the return spring, and meanwhile, parking is removed. The hand braking clamp structure is particularly applicable to parking and braking of desert steel tube vehicles.

Description

A kind of hand braking clamp structure

Technical field

The utility model relates to auto parts and components field, particularly relates to a kind of hand braking clamp structure.

Background technique

General desert steel pipe car is because trailing wheel is driving wheel, and after center of gravity leans on, so the braking force that trailing wheel need to be larger than front-wheel, so trailing wheel adopts multi-cylinder brake caliper conventionally, and multi-cylinder brake caliper is generally without parking function.

Model utility content

The utility model aims to provide a kind of hand braking clamp structure that is applicable to desert steel pipe car parking braking.

For realizing above-mentioned technical purpose, the utility model by the following technical solutions, a kind of hand braking clamp structure, caliper body is divided into two, centre is arranged symmetrically with two movably friction plates, gap in the middle of friction plate is provided with brake disc, one of them caliper body inside is processed with the cavity of arranging piston mechanism, the inside is provided with push-rod piston and advances swivel nut, push-rod piston and propelling swivel nut form a screw pair, zip rocking arm is by spline and rocking arm locking nut and advance swivel nut to fix, one end of push-rod piston is just inserted in the spline of gap adjusting strip, zip rocking arm links together by return spring and zip support.

As preferably, caliper body is by aluminum alloy processing and fabricating.

As preferably, two-part that caliper body is divided into are connected with four hexagon socket head cap screws.

As preferably, push-rod piston and to advance push-rod piston in the screw pair that swivel nut forms be four-head outside thread, advancing swivel nut is four-head internal thread.

As preferably, Hexagon is processed in one end of push-rod piston, is just inserted in the spline of gap adjusting strip.

Hexagon is processed in one end of push-rod piston of the present utility model, just be inserted in the spline of gap adjusting strip, therefore, push-rod piston can only move along self axis, pull zip rocking arm just can drive push-rod piston to move towards friction plate direction, realize parking hand brake function, unclamp zip rocking arm, under return spring effect, zip rocking arm is got back to again origin-location, now parking is removed, after friction disc wear, only need pull down gap adjusting strip, rotating push-rod piston just can be adjusted the gap between brake disc and friction plate, the utility model is specially adapted to the parking braking of desert steel pipe car.

Embodiment

Describe embodiment of the present utility model below in detail, described embodiment's example is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment who is described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.

Shown in Fig. 1 and Fig. 2, a kind of hand braking clamp structure, caliper body 1 is by aluminum alloy processing and fabricating, caliper body 1 is divided into two, the two-part that are divided into are connected with four hexagon socket head cap screws, centre is arranged symmetrically with two movably friction plates 2, gap in the middle of friction plate 2 is provided with brake disc, one of them caliper body 1 inside is processed with the cavity of arranging piston mechanism, the inside is provided with push-rod piston 3 and advances swivel nut 4, push-rod piston 3 and propelling swivel nut 4 form a screw pair, push rod is lived, 3 is four-head outside thread, advancing swivel nut 4 is four-head internal threads, zip Rocker arm 5 is by spline and rocking arm locking nut 6 and advance swivel nut 4 fixing, Hexagon is processed in one end of push-rod piston 3, just be inserted in the spline of gap adjusting strip 7, zip Rocker arm 5 links together by return spring 9 and zip support 8.

Hexagon is processed in one end of push-rod piston 3 of the present utility model, just be inserted in the spline of gap adjusting strip 7, therefore, push-rod piston 3 can only move along self axis, pull zip Rocker arm 5 just can drive push-rod piston 3 to move towards friction plate 2 directions, realize parking hand brake function, unclamp zip Rocker arm 5, under return spring 9 effects, zip Rocker arm 5 is got back to again origin-location, now parking is removed, after friction plate 2 wearing and tearing, only need pull down gap adjusting strip 7, rotating push-rod piston 3 just can be adjusted the gap between brake disc and friction plate 2, the utility model is specially adapted to the parking braking of desert steel pipe car.

In the description of this specification, the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or feature can be with suitable mode combinations in any one or more embodiments or example.
