Description

Engine roller rocker arm integrated unit

Technical Field

The utility model relates to a well formula camshaft engine field, concretely relates to engine roller rocking arm integrated unit.

Background

The roller rocker arm is used for driving the opening and the closing of the intake valve and the exhaust valve by utilizing the lift change of the camshaft during the rotation of the cam. The traditional roller rocker arm assembly is mostly composed of one or more roller rocker arm shafts, roller rocker arms and the like. During installation, the roller shaft is usually installed into the shaft hole of the rocker arm from one end of the machine body, and then the parts such as the end ring, the roller rocker arm, the spacer ring spacer bush and the like are sequentially installed in the camshaft chamber. Therefore, the existing roller rocker arm assembly not only has higher requirement on the machining precision of the shaft hole of the rocker arm of the engine body, but also has complex installation. When the rocker arm assembly is disassembled and inspected, parts such as the rocker arm shaft, the roller rocker arm and the like need to be sequentially drawn out, and the roller rocker arm assembly of a certain cylinder cannot be independently inspected or replaced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to provide an engine roller rocking arm integrated unit of convenient dismantlement installation.

The utility model discloses a realize through following technical scheme:

an engine roller rocker arm integrated unit comprises a cover plate, a roller rocker arm shaft and a plurality of roller rocker arm sub-components;

the cover plate is provided with a cavity which is concave upwards, and two ends of the roller rocker shaft are respectively fixed on the left wall and the right wall in the cavity; the plurality of roller rocker arm sub-components are sleeved on the roller rocker arm shaft through rocker arm shaft holes;

the roller rocker shaft is provided with a main oil duct along the axis direction, and is also provided with a plurality of oil distribution holes vertically communicated with the main oil duct, and the oil distribution holes are communicated with the rocker shaft holes in a one-to-one correspondence manner.

Furthermore, one end of the cover plate is provided with an oil inlet channel, and the oil inlet channel is communicated with the main oil duct.

Furthermore, the number of the roller rocker arm sub-components is four; and positioning rings are arranged at two ends of the roller rocker arm shaft.

Compared with the prior art, the utility model the beneficial effect who gains as follows:

the utility model discloses can correspond gyro wheel rocking arm axle and the gyro wheel rocking arm branch part of dismantling the corresponding cylinder of installation. Meanwhile, the main oil duct is matched with the oil inlet duct and the oil distributing hole, so that the roller rocker arm can rotate by parts conveniently, the abrasion is reduced, and the service life is prolonged.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

An engine roller rocker arm integrated unit as shown in fig. 1-3 mainly comprises a cover plate 1, a roller rocker arm shaft 2 and four roller rocker arm sub-components 3. A cavity which is concave upwards is arranged on the cover plate 1, and two ends of the roller rocker arm shaft 2 are respectively fixed on the left wall and the right wall in the cavity through bolts; the four roller rocker arm sub-components 3 are sleeved on the roller rocker arm shaft 2 through rocker arm shaft holes, and positioning rings are arranged at two ends of the roller rocker arm shaft 2 to prevent the roller rocker arm sub-components from shaking left and right.

The roller rocker shaft 2 is provided with a main oil duct 4 along the axis direction, the roller rocker shaft 2 is further provided with four oil distribution holes 5 vertically communicated with the main oil duct 4, and the oil distribution holes 5 are communicated with the rocker shaft holes in a one-to-one correspondence mode. An oil inlet channel 6 is arranged at one end of the cover plate 1, the oil inlet channel 6 is communicated with the main oil channel 4, and an oil stringing pipe is installed on the oil inlet channel 6.

In this embodiment, a plurality of engine roller rocker arm integrated units constitute a roller rocker arm group side by side, and when a certain position is bad, only need dismantle corresponding partial integrated unit can.
