Description

Technical Field

[0001] The utility model relates to a rocker arm brake which is convenient for wiring. Background Art

[0002] The engine rocker arm brake requires a biasing structure to bias the brake toward the valve bridge or cam side to prevent the rocker arm from detaching during the swing process, causing collision damage and noise. The common biasing structure of the independent rocker arm is to use the biasing spring on the biasing spring rod to press the brake rocker arm against the cam, always keeping the brake rocker arm roller in contact with the cam. The biasing spring rod needs to be fixed to a certain part of the cylinder head, and one structure is to fix it to the camshaft seat. Figure 1 As shown, the spring rod A is installed on the rocker arm shaft seat B; usually more than two spring rods are required, and they are stacked to prevent errors. This method has the following disadvantages: due to the need for a certain installation height, a spacer of a certain height is required at the lower end of the spring rod mounting bolt; the installation position of the spring rod is usually inconsistent with the height of the top of the bias spring C, and the spring rod needs to be bent and formed in multiple steps, which increases the manufacturing cost. Summary of the Invention

[0003] The purpose of the utility model is to provide a rocker arm brake which is convenient for wiring and can effectively reduce the manufacturing cost.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rocker brake that is easy to wire, which includes a rocker shaft mounting bracket, a rocker shaft mounted on the rocker shaft mounting bracket, a rocker and a spring rod mounted on the rocker shaft, the brake also includes a bracket mounted on the rocker shaft and a wiring harness plate, the lower end surface of the bracket matches and fits with the circumferential surface of the rocker shaft, and a first connecting hole, a second connecting hole and a third connecting hole are provided on the bracket, the bracket is fixedly connected to the rocker shaft by a first bolt assembly on the first connecting hole, the spring rod is fixedly connected to the bracket by a second bolt assembly on the second connecting hole, and the wiring harness plate is fixedly connected to the bracket by a third bolt assembly on the third connecting hole.

[0005] In another embodiment, a main wiring groove and a plurality of auxiliary wiring grooves communicating with the main wiring groove are formed on the wiring harness plate.

[0006] In another embodiment, an upwardly protruding mounting column is formed on the bracket, the third connecting hole is formed on the upper end surface of the mounting column, a sleeve is formed on the outer surface of the side wall of the wiring harness plate forming the main wiring groove, the sleeve is sleeved on the mounting column and the third bolt assembly is threadedly connected to the third connecting hole and then pressed on the upper end surface of the sleeve.

[0007] In another embodiment, the main wiring groove is arranged along an axial direction parallel to the rocker arm shaft, and the auxiliary wiring groove is arranged perpendicular to the main wiring groove.

[0008] In another embodiment, an annular wire harness ring is provided in the main wiring groove, and the wires are arranged on the wire harness plate and passed through the wire harness ring.

[0009] In another embodiment, the main wiring trough is provided with a plurality of convex strips arranged along its length direction for separating the wires.

[0010] Due to the application of the above technical solution, the present invention has the following advantages compared with the existing technology: the biasing spring rod is directly installed on the bracket without the need for a pad; the spring rod can be made into a flat plate and does not require bending, so the manufacturing cost is low; the connection between the two spring rods does not require overlapping installation; this bracket also integrates the mounting hole of the wiring harness bracket, which facilitates the installation of the wiring harness bracket.
