Description

Novel engine suspension
Technical Field
The utility model relates to an automobile part, a novel engine mounting specifically says so.
Background
With the new national regulation, the light weight of the medium and heavy truck is accelerating popularization and implementation. At present, heavy truck suspension in China mostly adopts cast steel and cast iron structures, the heavy truck suspension has excessive strength performance while having large weight, and light-weight structural forms of full cast aluminum, half cast aluminum, magnesium alloy and the like are increasingly used, wherein the structural forms of embedded nuts are also different, and the heavy truck suspension is particularly reflected in the aspects of cost, forming mode and using performance. In addition, along with the weight increase and the output torque increase of the power assembly system of the commercial vehicle, the requirement on the fatigue life of the engine suspension is increased, and the engine suspension is required to meet the requirements under different working conditions.
Disclosure of Invention
In order to solve the above problems, the present invention provides a novel engine mount.
The utility model discloses a realize above-mentioned purpose, a novel engine mount, including the exoskeleton, the inner frame, rubber buffer block and the fixed plate of setting side about the exoskeleton, the inner frame vulcanizes together through rubber buffer block, at the fixed plate, exoskeleton middle part and inner frame upper surface are provided with the embedded nut who runs through respectively and perforate, the fenestrate both ends of embedded nut are for the middle part broad, the interior casting of embedded nut is fenestrate has integrative embedded nut, embedded nut comprises the annular arch of a screw section of thick bamboo and screw section of thick bamboo both ends setting, the protruding diameter of annular is greater than the screw section of thick bamboo diameter of middle part.
Preferably, the peripheral cross section of the annular protrusion is polygonal.
Preferably, the inner frame is perpendicular to the embedded nut through hole on the fixing plate.
Preferably, the front side of the outer framework is provided with an integrated arc-shaped supporting plate with an inverted isosceles trapezoid vertical cross section, the top of the arc-shaped supporting plate is open, and the inner framework is vulcanized with the inner side surface of the arc-shaped supporting plate through a rubber buffer block, so that the inner framework is supported on the outer framework in a splayed manner.
Preferably, the lower surface of the arc-shaped support plate is provided with a reinforcing rib integrated with the exoskeleton.
The utility model discloses simple structure reduces the atress of outer skeleton when power assembly lateral shifting, reduces outer skeleton backup pad fracture ratio. The clearance between the rubber vulcanization body assembly and the base is eliminated through interference fit, so that the engine shake caused by looseness is reduced. Greatly prolongs the service life of the shock pad, and has obvious economic advantage and practical advantage.
In addition, compare present most embedded nuts, the utility model discloses an embedded nut is with low costs, and same screw thread is small, and simple manufacture prevents changeing, tensile off-line performance is good. The embedded nut is cast together with the engine suspension inner frame and the base, and is connected with the bolt during loading.
The method is mainly embodied in the following points:
firstly, the total amount of the embedded nuts adopted by the light weight suspension of the traditional heavy truck is about 70-75g by taking M14 multiplied by 1.5-6H as an example, the weight of the embedded nuts of the front suspension of the novel engine is about 35g, the average weight of each embedded nut can be reduced by about 35-40g, the weight is reduced by about 50%, and the embedded nuts with different specifications and different thread depths can be used in the structure (for example, the embedded nuts with the specifications of M18, M20, M22 and the like, and the thread depths of 10mm, 20mm, 30mm and the like).
Secondly, the novel engine is suspended with embedded nuts, and a multi-edge stretching and lathe turning anti-pulling groove-removing mode is adopted. Most of the existing embedded nuts adopt the form of casting combined machining and full machining, and compared with the prior art, the embedded nut has the advantages of reduced cost, improved efficiency and no limitation of production equipment.
And the novel embedded nut for the engine suspension has the advantages of positioning at two ends, rotation prevention after stress and high anti-pulling performance.
