Abstract

The utility model relates to an automatic regulation arm for braking gap, carry out rotatory control arm including the relative casing of casing, worm, thrust gasket, end face bearing and ability, worm, thrust gasket, end face bearing all set up in the casing, the thrust gasket sets up between worm and end face bearing, adopt the line contact between the tip of worm and the thrust gasket. The utility model discloses the design of worm tip and thrust gasket has been changed to automatic regulation arm for braking gap self -modulation arm, changes the line contact into from original conical contact cooperation (face contact) to frictional force has been reduced, the customer's installation of being convenient for.

Description

Automatic reglation arm for braking gap

Technical field

The utility model is related to automatic reglation arm for braking gap.

Background technology

Self-regulated arm worm screw uses new end face support structure, employs a kind of conical surface between worm screw end face and end face bearing Contact thrust washer, using the contact with face for the face.Due to using cone match pad between worm screw and end face bearing, rub Wiping power ratio is larger, and the control arm rotation torque of self-regulated arm worm screw finished product is larger, and client installs very laborious during self-regulated arm.

Utility model content

For overcoming disadvantages mentioned above, the purpose of this utility model is to provide one kind can reduce frictional force between pad and worm screw Automatic reglation arm for braking gap.

In order to reach object above, the technical solution adopted in the utility model is：A kind of automatic reglation arm for braking gap, bag Include housing, worm screw, thrust washer, end face bearing and the control arm that can be rotated, described worm screw, thrust pad relative to housing Piece, end face bearing are arranged in housing, and described thrust washer is arranged between worm screw and end face bearing, the end of described worm screw Linear contact lay is adopted and thrust washer between.Preferably, the end of described worm screw is provided with conical socket, and described thrust washer sets It is equipped with hemisphere jut, between the end of described worm screw and thrust washer, line is realized by the cooperation of conical socket and hemisphere jut and connect Touch.

Preferably, described hemisphere jut is integrally formed on described thrust washer, more firmly.

The utility model automatic reglation arm for braking gap self-regulated arm, have changed the design of worm end and thrust washer, from Originally taper-face contact cooperation（Face contacts）It is changed to linear contact lay, thus reducing frictional force, being easy to client and installing.

Brief description

Fig. 1 is the structural representation of the present embodiment；

Fig. 2 is the partial enlarged drawing at A in Fig. 1.

In figure：

1- worm screw；2- thrust washer；3- control arm；4 housings；5- hemisphere jut；6- conical socket.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model Define.

Referring to shown in accompanying drawing 1, a kind of automatic reglation arm for braking gap of the present embodiment, including housing 4, worm screw 1, thrust pad Piece 2, end face bearing and the control arm 3 that can be rotated relative to housing 4, worm screw 1, thrust washer 2, end face bearing are arranged at In housing 4, thrust washer 2 is arranged between worm screw 1 and end face bearing, is connect using line between the end of worm screw 1 and thrust washer 2 Touch, as shown in Fig. 2 the end of worm screw 1 is provided with conical socket 6, thrust washer 2 is provided with hemisphere jut 5, hemisphere jut 5 It is integrally formed on thrust washer 2, pass through joining of conical socket 6 and hemisphere jut 5 between the end of worm screw 1 and thrust washer 2 Linear contact lay is realized in conjunction.

Embodiment of above is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with this skill The people of art understands that content of the present utility model is simultaneously carried out, and can not limit protection domain of the present utility model with this, all The equivalence changes done according to the utility model Spirit Essence or modification, all should cover in protection domain of the present utility model.

Claims (3)
