Abstract
The utility model discloses a kind of crank connecting link, suitable for the crank connecting link of bent axle air pump, the body of rod of entire body is in circular-arc-shaped design at its both ends, and both ends are milled with the piston hole of connection piston component and the concave slot of connecting crank axle respectively, and the body of rod becomes larger from piston hole end to concave slot.The utility model is applied to bent axle air pump, one end is directly connected with jack shaft bearing, the other end connects piston component, power transmission efficiency is high, and body of rod entire body itself designs, and itself is milling out every link slot, therefore structural strength is higher, and the zinc-plated processing on surface, it can more increase the corrosion resistance of structure, so as to increase service life.
Description
Technical field
Transmission of crankshaft field is the utility model is related to, more particularly to a kind of crank connecting link.
Background technology
Bent axle air pump is the part for realizing that air spring automobile shock is critically important, is specifically used as air spring
Air bag provides gases at high pressure, and the generation of gases at high pressure is necessarily realized by the compression of air.
The air compression compression of reciprocating realization to gas in cylinder by piston, and the reciprocating motion of piston needs
Motor is wanted to provide power, and the transmission of motor power then needs shaft member to realize, and one kind can be driven, and can realizes that piston is past
The shaft member moved again, can only be often crank axle.
And in the transmission process of crank axle, crank connecting link is a critically important part, the effect of crank connecting link be by
The circular motion of crank axle is converted into the reciprocating motion of piston, and the crank connecting link in traditional engine construction is mainly by piston
Reciprocating motion be changed into the circular motion of bent axle, and rod member is mostly metal circumference type rod member, and sets connection at its both ends
Hidden danger be present in rod member intensity and service life in bearing, such design.
Utility model content
The utility model is overcomes above-mentioned drawback, there is provided a kind of crank connecting link, applied to the crank connecting link of bent axle air pump,
The crank connecting link one end is directly connected with jack shaft bearing, and other end connection piston component, power transmission efficiency is high, and body of rod sheet
Body entire body designs, and itself is milling out every link slot, therefore structural strength is higher, and the zinc-plated processing on surface, can more increase knot
The corrosion resistance of structure, so as to increase service life.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of crank connecting link, suitable for bent axle air
Pump, including the body of rod 1, the both ends of the body of rod 1 mill out piston hole 11 and concave slot 12 respectively, and the body of rod 1 is set in arc-shaped respectively at both ends
Meter, and the body of rod 1 becomes larger from the end of piston hole 11 to concave slot 12, piston hole 11 is connected with piston component, enables the body of rod 1
Enough passing powers are to piston component, and the body of rod 1 of monoblock type make it that the intensity of structure itself is big, can bear bigger torsion；
Further, concave slot 12 be specially upper level is smaller, less first cell body 121 of diameter and lower height compared with
Greatly, the second cell body 122 being relatively large in diameter；
Further, it is provided with bearing in concave slot 12；
Bearing is arranged in concave slot 12, and shape is agreed with the first cell body 121 and the second cell body 122, and crank axle and axle
Hold and agree with, stability is high, and crank connecting link is moved with the motion of crank axle；
Further, the body of rod 1 is aluminum alloy material, and overall zinc-plated processing, surface zinc-plated processing can increase the body of rod 1
Anticorrosive, anti-corrosion ability, so as to increase the service life of structure, and it is zinc-plated after, structure is more attractive.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Applied to bent axle air pump, one end is directly connected with jack shaft bearing, and other end connection piston component, direct passing power will
The circular motion of crank axle is converted into the reciprocating motion of piston so that and power transmission efficiency is high, and entire body design of the body of rod 1 itself,
And every link slot itself is being milled out, the hardness of aluminium alloy in itself is big, and intensity is high, therefore structural strength is high, and the zinc-plated place on surface
Reason, can more increase the corrosion resistance and resistant to rust ability of structure, so as to increase service life, and the zinc-plated processing on surface to tie
Structure is more attractive.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Section A-A schematic diagram in Fig. 1.
Wherein：1st, the body of rod；11st, piston hole；12nd, concave slot；121st, the first cell body；122nd, the second cell body.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment 1：
A kind of crank connecting link, as shown in Fig. 1~2, the body of rod 1 of entire body is in circular-arc-shaped design at its both ends, and both ends are distinguished
The piston hole 11 of connection piston component and the concave slot 12 of connecting crank axle are milled with, and the body of rod 1 is from the end of piston hole 11 to convex
Type groove 12 becomes larger.
Above, concave slot 12 be specially upper level is smaller, less first cell body 121 of diameter and lower height compared with
Greatly, the second cell body 122 being relatively large in diameter, and bearing is provided with concave slot 12, bearing shape and first groove in concave slot 12
The cell body 122 of body 121 and second agrees with completely, and crank axle agrees with bearing, and stability is high, and enable crank connecting link with
The motion of crank axle and move.
Preferably, the body of rod 1 is aluminum alloy material, and overall zinc-plated processing, surface zinc-plated processing can increase the anti-of the body of rod 1
Burn into anti-corrosion ability, so as to increase the service life of structure, and it is zinc-plated after, structure is more attractive.
Utility model works principle and use process are as follows：
Crank axle is connected in the bearing in concave slot 12, and piston component passes through piston hole 11 and rod member by fixing axle
1 fixes, and fixing axle can rotate in piston hole 11, and crank axle is in the case of circular motion, because piston component leads to
Cross fixing axle to fix with the body of rod 1, therefore crank axle pulls in piston component piston along cylinder slide so that piston is reciprocating.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The people of art can understand content of the present utility model and implement according to this, can not limit the scope of protection of the utility model with this.
All equivalent transformations done according to the utility model Spirit Essence or modification, should all cover the scope of protection of the utility model it
It is interior.
