Abstract
The utility model discloses an engine wayshaft bed comprising a wayshaft body, on which is arranged an up plane and a down plane connected with a fixed pylome between, a vittae pylome provided on the wayshaft body to connect the up plane with the down plane and a socket equipped on the down plane communicated with the vittae pylome. The utility model is not only capable of conveniently realizing pressure-feed oiling to the EVB system but also saving the space.
Description
Technical field
The utility model relates to a kind of technical field of motor, especially relates to a kind of engine rocker axle bed that can be used on the motor.
Background technique
At present, continuous development along with society and economic construction, the use of heavy goods vehicles is more and more, the design of its carrying capacity is also in continuous increase, for people's security needs in use, to the security requirement of heavy goods vehicles also in continuous raising, so, can improve the Safety performance of vehicle driving and braking a kind of new technology---EVB technology is widely used on the motor of vehicle by people.Because the EVB system need carry out forced feed to its system in work, this just requires to arrange that oil circuit is its fuel feeding, no matter but at present be at the engine rocker cover inside, or cylinder head on arrangement space all be very limited, it is very difficult to increase pipeline again, therefore, how to be that EVB system fuel feeding and the fuel feeding oil duct how the EVB system reasonably is set are the previous problems that presses for solution of people's order.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of engine rocker axle bed, and it not only can realize the forced feed to the EVB system easily, and has saved the space.
For solving the problems of the technologies described above, the technical solution of the utility model is: the engine rocker axle bed, comprise the rocker shaft bed body; the rocker shaft bed body has last plane and lower plane; upward connection is provided with fixed via between plane and the lower plane; also be provided with the oil duct through hole that plane and lower plane are gone up in connection on the described rocker shaft bed body, described lower plane is provided with the groove that is communicated with the oil duct through hole.
As a kind of optimal way, the bottom of described rocker shaft bed body is provided with the cavity that is communicated with lower plane, and the lower ending opening of described fixed via is in cavity.
Adopting the engine rocker axle bed of said structure, is to support rocking arm because the engine rocker axle bed mainly acts at cylinder covering position and its, so the processing oil duct is very suitable on rocker shaft bed.To be arranged at the inside of rocker shaft bed for the oil duct of EVB system fuel feeding, this has not only realized the forced feed to the EVB system easily, and has simplified the structure of motor, has saved the space of motor.Employing is provided with the structure of cavity on the rocker shaft bed body, alleviated the quality of rocker shaft bed body, has reduced cost.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is that engine rocker axle bed of the present utility model has structural representation;
Fig. 2 is that A---A is to sectional view.
Embodiment
See figures.1.and.2, a kind of engine rocker axle bed of the present utility model is: comprise rocker shaft bed body 1, plane 11 and lower plane 12 on having on the rocker shaft bed body 1, for the secure rocker seat body, between last plane 11 and lower plane 12, be communicated with and be provided with fixed via 2, can rocker shaft bed body 1 be fixed on the body by fixed via 2, in order to realize forced feed to the EVB system, on rocker shaft bed body 1, also be provided with the oil duct through hole 3 on plane 11 and lower plane 12 in the connection, when when carrying out the installation of motor, the position of oil duct through hole 3 might can not align with the position of engine cylinder cap upper oil hole, can on rocker shaft bed body 1 lower plane 12, process a groove 4, groove 4 is communicated with the opening of oil duct through hole 3 on lower plane 12, this just can introduce oil in the oil duct through hole 3 by groove 4, enter the oil duct of pitman arm shaft behind the last plane 11 of pressure oil arrival, arriving at last is EVB system fuel feeding; And, in order to improve the firm reliability that rocker shaft bed body 1 is installed, want symmetry on the relative whole rocker shaft bed body 1 in the position in 2 liang of holes of oil duct through hole 3 and fixed via, and can adopt the diameter of oil duct through hole 3 bigger than the diameter of fixed via 2, like this, just can make oil duct through hole 3 not only can be EVB system fuel feeding, and can play fixation as fixed via 2.In order to alleviate the quality of rocker shaft bed body 1, but also to guarantee its intensity as far as possible, can be provided with a cavity 5 that is communicated with lower plane 12 in the bottom of rocker shaft bed body 1, and the lower ending opening of fixed via 2 be in cavity 5.
This engine rocker axle bed not only can be realized support to rocking arm as usual engine rocker axle bed, but also can realize the forced feed to the EVB system on the motor, has simplified the structure of motor, the arrangement space of having saved motor.
