Abstract
The invention belongs to the technical field of a vehicle engine, particularly relates to a novel engine cam shaft bearing cover. A chain guiding element, through which a timing chain passes, is fixedly arranged above the bearing cover. The above technical proposal shows that the bearing cover is fixedly provided with a chain guiding element, and the timing chain passes through the chain guiding element and steadily and orderly rotates under the guiding of the chain guiding element, thus the stable operation of the timing chain is guaranteed, and the stable operation of the cam shaft, even the engine, is guaranteed.
Description
Technical field
The invention belongs to technical field of automobile engine, be specifically related to a kind of novel engine camshaft bearing cover.
Background technique
The bent axle of motor comes the drive cam shaft operation to rotate through timing chain; And control the normal opening and closing of intake valve and exhaust valve thus; Phenomenon such as play about if timing chain occurs in running; With the normal operation that directly influences camshaft, and then badly influence the functional reliability of motor.
Summary of the invention
The purpose of this invention is to provide a kind of novel engine camshaft bearing cover, it can guarantee that timing chain can normally move with security and stability.
For realizing above-mentioned purpose, the present invention has adopted following technological scheme: a kind of novel engine camshaft bearing cover, the upper fixed of bearing cap are provided with the chain guide spare that supplies timing chain to pass through.
Can know by technique scheme; The present invention has fixedly installed chain guide spare on bearing cap; Timing chain passes in the chain guide spare since then; And the operation of steady ordered ground is rotated under the guiding of chain guide spare, thereby has guaranteed the stable operation of timing chain, has also guaranteed the stable operation of camshaft and even motor.
Description of drawings
Fig. 1 is an assembly structure schematic representation of the present invention;
Fig. 2 is the structural representation of bearing cap.
Embodiment
As shown in Figure 1, a kind of novel engine camshaft bearing cover, the upper fixed of bearing cap 10 is provided with the chain guide spare 20 that supplies timing chain 30 to pass through.
The lower end of chain guide spare 20 can be set directly at the top of bearing cap 10, and is as shown in Figure 2 as preferred version of the present invention, and described bearing cap 10 is provided with boss 11, and chain guide spare 20 is connected for bolt with boss 11.
Being provided with of boss 11 is beneficial to the structural strength that strengthens bearing cap 10, also helps guaranteeing simultaneously the stable operation of chain guide spare 20.
As shown in Figure 2, as the further preferred version of the present invention, described boss 11 is arranged between two bearing holes 12 of bearing cap 10, and this set not only can strengthen the structural strength of bearing cap 10, also helps improving simultaneously the integrity of bearing cap 10.
As shown in Figure 1; One end of described chain guide spare 20 is fixed on the bearing cap 10; The other end extends upward and its end is kink shape, and the folder of described timing chain 30 portion from the termination of kink shape passes in the air, thereby helps limiting timing chain 30 play up and down in the course of the work.
Rotate in order better to play the guiding and the operation of stable timing chain 30, the length along the chain through direction of described chain guide spare 20 reduces from top to bottom gradually, in Fig. 1, promptly shows as the big up and small down upside-down triangle shape of chain guide spare 20.
As preferred version of the present invention, as shown in Figure 2, be provided with hollow part 13 between two bearing holes 12 of described bearing cap 10.
The setting of hollow part 13 helps alleviating the weight of bearing cap 10, also can reduce manufacturing cost simultaneously.
The cross section of hollow part 13 has the multiple choices mode, and as preferred version of the present invention, the cross section of described hollow part 13 is ellipticity or rectangular-shaped, helps manufacturing and improves work efficiency.
As shown in Figure 2, the long axis direction of described hollow part 13 and the bearing of trend of camshaft are perpendicular.
The above-mentioned set-up mode of hollow part 13 can guarantee the structural strength of bearing cap 10 when alleviating pts wt, help the stable operation of bearing cap 10.
As shown in Figure 2, described cross section is that four jiaos of places of rectangular-shaped hollow part 13 all adopt round-corner transition, and this processing mode is difficult for producing stress to be concentrated, and helps improving the force-bearing situation at hollow out place.
