Abstract
The invention belongs to the technical field of automobile parts, and particularly relates to a chain board. The chain board comprises a board body, the front face of the board body is rectangular, outwards-convex arc-shaped faces are connected to the lateral portions of the two short edges of the board body, long-strip-shaped short convex strips parallel to the short edges of the board body are arranged on the outwards-convex arc-shaped faces, arc faces are located at the ends, close to the long-strip-shaped short convex strips, of long-strip-shaped holes, the circle centers of the arc faces are the same as the circle centers of the outwards-convex arc-shaped faces, and an arc-shaped concave part and the long-strip-shaped holes are in slope transition. The chain board is simple in structure, stress borne by the chain board can be well reduced, the use strength can be greatly improved, and the service life is prolonged.
Description
Technical field
The invention belongs to auto parts apparatus technical field, more particularly, to a kind of carrier bar.
Background technology
Carrier bar is belonging to the part in auto parts and components, is mainly used for automotive trannsmission system and uses.Carrier bar and carrier bar it
Between, the material nonhomogeneous hardness between carrier bar and bearing pin larger, long-time CONTACT WITH FRICTION, especially in road conditions difference and Ackermann steer angle chain
Wear and tear between plate and bearing pin larger, cause carrier bar inordinate wear for a long time.The unreasonable design of carrier bar also can make carrier bar stress
Unreasonable, crackle from stress raiser in carrier bar, and prolonged exercise can rupture.
Content of the invention
It is an object of the invention to solving the problems, such as techniques discussed above, provide a kind of carrier bar, its technical scheme is as follows:
It is characterised in that described carrier bar includes plate body, the front of plate body is rectangle to a kind of carrier bar, and two of plate body short
The sidepiece on side is connected with evagination arcwall face, and described evagination arcwall face is provided with the short raised line of the strip parallel with the minor face of plate body；
The middle of the sidepiece on two long sides of plate body is provided with the long raised line of strip, and the long raised line of strip is parallel with the long side of plate body, institute
The two ends of the long raised line of strip stated are provided with to prominent projection in plate body；The middle of plate body offers arc-shaped recess portion, arc
The centre of shape depressed part offers through hole；It is located on plate body and offer strip between arc-shaped recess portion and the short raised line of strip
Hole, the end that elongate holes are located near the short raised line of strip is arc surface, arc surface and evagination arcwall face concentric, described
Arc-shaped recess portion and elongate holes between chamfered transition.
The carrier bar that the present invention provides, when in use, setting bearing pin in elongate holes, elongate holes are so that bearing pin
The space installed is bigger, is easily installed bearing pin.The through hole that the centre in arc-shaped recess portion opens up is used for fixing carrier bar use.Strip is long
Draw-in groove is defined, so that the connection between carrier bar and carrier bar is more stable between raised line and the short raised line of strip.Strip
The two ends of the long raised line of shape are provided with and can form barrier effect to bearing pin to prominent projection in plate body, place coming off of bearing pin.
The invention has the beneficial effects as follows:
Present configuration is simple, can be good at reducing the stress that carrier bar is subject to, can greatly strengthen use intensity, increases
Plus service life.
Brief description
Fig. 1 is the schematic diagram of the present invention.
Specific embodiment
With reference to Fig. 1 specific illustrative embodiment:
It is characterised in that described carrier bar includes plate body 1, the front of plate body 1 is rectangle to a kind of carrier bar, two of plate body 1
The sidepiece of minor face is connected with evagination arcwall face 2, and it is short that described evagination arcwall face 2 is provided with the strip parallel with the minor face of plate body 1
Raised line 3；The middle of the sidepiece on two long sides of plate body 1 is provided with the long raised line of strip 4, the length of the long raised line of strip 4 and plate body 1
Side is parallel, and the two ends of the long raised line of described strip 4 are provided with to prominent projection 5 in plate body 1；The middle of plate body 1 offers
Arc-shaped recess portion 6, the centre in arc-shaped recess portion 6 offers through hole 7；Arc-shaped recess portion 6 and the short raised line of strip are located on plate body 1
Elongate holes 8 are offered, the end that elongate holes 8 are located near the short raised line of strip 3 is arc surface 9, arc surface 9 between 3
With evagination arcwall face 2 concentric, inclined-plane 10 transition between described arc-shaped recess portion 6 and elongate holes 8.
The carrier bar that the present invention provides, when in use, setting bearing pin in elongate holes, elongate holes are so that bearing pin
The space installed is bigger, is easily installed bearing pin.The through hole that the centre in arc-shaped recess portion opens up is used for fixing carrier bar use.Strip is long
Draw-in groove is defined, so that the connection between carrier bar and carrier bar is more stable between raised line and the short raised line of strip.Strip
The two ends of the long raised line of shape are provided with and can form barrier effect to bearing pin to prominent projection in plate body, place coming off of bearing pin.
