Abstract
An elastic connecting piece is a two-stage elastic connecting piece. A push rod penetrates through a hole in a connecting shaft, a nut is connected with the push rod through threads, an adjusting nut is connected with the threaded part of the connecting shaft through threads, a spring is sleeved on the connecting shaft, one end of the spring is elastically connected with the nut, the other end of the spring is elastically connected with the adjusting nut, a screw fixedly connects a scaleplate and the connecting shaft, and a positioning scale and a service braking force adjusting range scale are formed on the scaleplate. When the push rod of a hydraulic driver is at a service braking position, a braking frame is adjusted to enable the positioning scale to be aligned with the appointed plane of the nut, the position of the adjusting nut is adjusted to enable the appointed plane of the adjusting nut to correspond to a certain position of the service braking force adjusting range scale, thus all adjusting work is finished, and the adjusting method is simple and accurate. All brakes on the same vehicle can be collectively adjusted with the same parameters according to the scales on the scaleplate respectively, so that the braking forces of all the brakes can be guaranteed to be the same.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic driver of two-stage type drum brake and the connection set of brake bracket, especially can make break produce the Flexible Connector of dual unit power by hydraulic driver.
Background technique
At present, the link that the known hydraulic driver that makes break is connected with brake bracket is all fixing or single-stage, by the symmetrical hinge of coupling shaft, to be passed the fraising of brake bracket triangular splint, the push rod of hydraulic driver is through the axial bore of coupling shaft, and the nut of push rod termination is fixedly connected with push rod or is connected with coupling shaft elasticity by a spring with coupling shaft.But the mode that push rod is fixedly connected with coupling shaft can not adapt to two-stage type braking completely, for two-stage type break, there is the consistent defect of each brake braking force that regulation technology requirement is high, be not easy to guarantee same chassis in single-stage Flexible Connector.
Summary of the invention
In order to overcome existing link, be not suitable with two-stage type break, regulation technology requires the high consistent deficiency of each brake braking force that is not easy to guarantee same chassis, the utility model provides a kind of two-stage Flexible Connector, this two-stage Flexible Connector not only can adapt to the usage requirement of two-stage type break, and can facilitate accurately regulating brake force as required.
The utility model solves the technological scheme that its technical problem adopts: push rod is through the hole of coupling shaft, nut is threaded with push rod, adjusting nut is threaded with the helical thread portion of coupling shaft, and spring housing is on coupling shaft, and one end is connected the other end and is connected with adjusting nut elasticity with nut elasticity.By adjustable brake frame, coupling shaft bottom and the step of push rod are disengaged, change adjusting nut position and make break reach corresponding duty power, just completed accurately whole adjusting work.Under the action of hydraulic driver coordinates, break can reliably complete and declutch, the repertoire of service braking, stopping brake.
The beneficial effects of the utility model are, under can coordinating in the action of hydraulic driver, break are reliably completed to declutch, whole braking maneuvers of service braking, stopping brake, and regulating method is simple, accurately.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is half section structural drawing of the present utility model.
Fig. 2 is the mounting structure schematic diagram of scale.
1. nuts in figure, 2. spring, 3. adjusting nut, 4. coupling shaft, 5. push rod, 6. scale, 7. screw, 8. duty power regulation range graduation line, 9. location graduation line.
Embodiment
In Fig. 1, push rod (5) is through the hole of coupling shaft (4), nut (1) is threaded with push rod (5), adjusting nut (3) is threaded with the helical thread portion of coupling shaft (4), it is upper that spring (2) is enclosed within coupling shaft (4), and one end is connected the other end and is connected with adjusting nut (3) elasticity with nut (1) elasticity.
In Fig. 2, push rod (5) is through the hole of coupling shaft (4), nut (1) is threaded with push rod (5), adjusting nut (3) is threaded with the helical thread portion of coupling shaft (4), spring (2) is enclosed within on coupling shaft (4), one end is connected the other end and is connected with adjusting nut (3) elasticity with nut (1) elasticity, screw (7) is fixedly connected with scale (6) with coupling shaft (4), have location graduation line (9) and duty power regulation range graduation line (8) on scale.At hydraulic driver push rod (1) in service braking position, adjustable brake frame makes the agreement planar registration of location graduation line (9) and nut (1), regulate adjusting nut (3) position to make a certain position of its agreement corresponding duty power regulation range graduation line of plane (8), just completed whole adjusting work, regulating method is simple, accurate.Each break of same chassis carries out according to the scale on scale unified adjusting that parameter is consistent respectively, can guarantee that the braking force of each break is consistent.
Claims (1)
1. a two-stage Flexible Connector, push rod is through the hole of coupling shaft, and nut is threaded with push rod, it is characterized in that: adjusting nut is threaded with the helical thread portion of coupling shaft, spring housing is on coupling shaft, and one end is connected the other end and is connected with adjusting nut elasticity with nut elasticity.
