Abstract
The present invention discloses a kind of commercial vehicle engine fixing device, including reinforcing plate in longeron (1), mounting bracket (3) and engine mounting (5), reinforcing plate (1) side is used to be fixedly connected with commercial car side rail inner in the longeron, its opposite side is connected with the vertical arm of mounting bracket (3), the engine mounting (5) is fixed on the horizontal arm of mounting bracket (3), and its free end is used to be connected with engine.The engine mount of the present invention, can make engine sink in collision process, reduce or avoid engine from invading driver's cabin, improve Vehicle Passive Safety.
Description
Technical field
Under making engine in collision process the invention belongs to automotive safety protection-gear technical field, particularly one kind
It is heavy, reduce or avoid engine from invading driver's cabin, improve the commercial vehicle engine fixing device of Vehicle Passive Safety.
Background technology
In vehicle collision safety, the living space of driver's cabin is vital.The engine behind front wheel of general passenger car,
When also having corresponding concave design the vehicle is collided, engine sinks or fallen on the ground, so as to avoid invading crew module's shadow
Ring the living space of occupant.And in general commercial car, engine is in the back lower place of crew module, in collision process, longeron occurs
Crumple, engine can invade the floor of driver's cabin due to effect of inertia, increase the deformation extent of driver's cabin, had a strong impact on and driven
The living space for the person of sailing.
Therefore, the problem of prior art is present be：Commercial vehicle engine fixing device in an impact, is easily caused engine
Driver's cabin is directly invaded, vehicle passive security is poor.
The content of the invention
It is an object of the invention to provide a kind of commercial vehicle engine fixing device, under engine can be made in collision process
It is heavy, reduce or avoid engine from invading driver's cabin, improve Vehicle Passive Safety.
The technical solution for realizing the object of the invention is：
A kind of commercial vehicle engine fixing device, including reinforcing plate, mounting bracket and engine mounting in longeron, it is described vertical
Reinforcing plate side is used to be fixedly connected with commercial car side rail inner in beam, the vertical arm connection of its opposite side and mounting bracket, institute
State engine mounting to be fixed on the horizontal arm of mounting bracket, its free end is used to be connected with engine, the mounting bracket
Vertical arm is fixedly connected with horizontal arm.
Preferably, in the longeron reinforcing plate and the vertical arm of mounting bracket by a cylindrical hinge and bolt connection,
The hinge is in longeron on the downside of reinforcing plate, and the bolt on the upside of reinforcing plate, is set in longeron in longeron in reinforcing plate
There is circular arc to induce groove, the induction groove is using the hinge as the center of circle, and origin or beginning is close to the bolt, and terminal is towards before commercial car
Side.
The present invention compared with prior art, its remarkable advantage：
Commercial vehicle engine sink structures pass through the shape and and bolt hole to guide groove in the circular arc on side rail
The design of relative position, so that ensure the structural strength of the fixing device of engine in normal vehicle operation, and in vehicle
Collision process engine is according to using cylindrical hinge as pivot, and the track along induction groove sinks, and reduces engine along longeron
The displacement in direction, reduces the intrusion volume to cab floor, increases the living space of driver's cabin, and by inducing the width of groove
Degree successively decreases, and bolt is extruded with induction groove, and reinforcing plate deforms in longeron, absorbs energy, improves the passive security of vehicle
Performance.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of commercial vehicle engine fixing device of the present invention.
Fig. 2 is the structural representation of reinforcing plate in longeron in Fig. 1.
In figure, reinforcing plate in 1 longeron, 2 induction grooves, 3 mounting brackets, 31 baffle plates, 4 block rubbers, the suspension of 5 motivations, 6 hinges, 7
Bolt.
Embodiment
As shown in figure 1, commercial vehicle engine fixing device of the present invention, including reinforcing plate 1, mounting bracket 3 and hair in longeron
The side of reinforcing plate 1 is used to be fixedly connected with commercial car side rail inner in motivation suspension 5, the longeron, its opposite side and suspension branch
The vertical arm connection of frame 3, the engine mounting 5 is fixed on the horizontal arm of mounting bracket 3, and its free end is used for and engine
Connection, the vertical arm of the mounting bracket 3 is fixedly connected with horizontal arm.
Reinforcing plate 1 is connected with the vertical arm of mounting bracket 3 by a cylindrical hinge 6 and bolt 7 in the longeron, described
Hinge (6) is close to the downside of reinforcing plate in longeron 1, the bolt 7 upside of reinforcing plate 1 in longeron, in longeron in reinforcing plate 1
Groove 2 is induced provided with circular arc, the induction groove 2 is the center of circle with the hinge 6, and origin or beginning is close to the bolt 7, and terminal direction is commercial
Front side.
As shown in Fig. 2 the width of the induction groove 2 is gradually reduced from origin or beginning to terminal, its origin or beginning width is equal to the spiral shell
The diameter of bolt 7.
When a vehicle is in a collision, due to stress concentration at circular arc induction groove 2, and rigidity is relatively low, deforms first,
When impact energy is sufficiently large, bolt 7 cuts the sheet material that bolt hole induces groove with circular arc, so as to guide engine along circular arc
Shape lures guide groove movement, controls the movement locus of engine, it is sunk, and reduces or avoids engine to the intrusion volume of driver's cabin,
Increase the living space of driver and occupant.And the width gradual change degree of circular arc induction groove decides mounting bracket to engine
The absorbing state of inertia energy.
Speed and energy that the width gradual change degree of different circular arc induction grooves 2 can influence the track of engine to run
Absorption.
Circular arc induces the distance between groove 2 and bolt hole 9 to be designed according to different automobile types, and which determine bolt
7 cut the minimal impact energy of sheet material between induction groove and bolt hole, that is, decide the minimal impact energy that engine sinks.
As optimization, the bolt 7 is two, is arranged with the hinge 6 into isosceles triangle.
Thus, when vehicle does not collide, the connection arrangement of 3 point types ensure that the fixed effective of engine.
