Description
Technical field
The utility model relates to a kind of independent front suspension system of automobile, relate in particular to the light and little automobile of rangeability of load in the heavier but front axle zone of a kind of carload, the independent front suspension system of light truck, passenger vehicle for example, this independent front suspension system comprises the independent front suspension assembly.In addition, the utility model also relates to a kind of automobile with independent front suspension system.
Background technology
At present, the front suspension of automobiles such as truck, passenger vehicle generally adopts the dependent suspension system, and this dependent suspension system comprises the dependent suspension assembly of being made up of parts such as whole vehicle bridge and steel springs.The dependent suspension of forms such as steel spring is simple in structure, easy to maintenance, cost is low, and can adapt to the variation significantly of automobile load capacity.But, dependent suspension is owing to adopt rigid axle or front axle, therefore unsprung weight (is a nonspring carried mass, the quality that comprises parts such as wheel, wheel hub, vehicle bridge, suspension member) bigger, be subjected to road shocks in the process of moving when automobile and beat or when vibrating, the quality of carrying parts owing to non-spring is bigger, so the vibrational energy of these parts is also very big, and these vibrational energies need be delivered on the vehicle frame by suspension.But, in above-mentioned dependent suspension, because the arrangement space in automobile front axle zone is limited, steel spring is generally shorter along the length (being steel spring holder distance) of automobile longitudinal direction, the rigidity of steel spring itself is also bigger simultaneously, this can make vibrational energy almost not decay, cushion and be directly delivered on the vehicle frame, thereby makes vehicle frame and the body portion high vibration that is carried by vehicle frame, and the ride comfort of running car, the traveling comfort of taking reduce greatly.And, because the dependent suspension system adopts rigid axle or axletree, and left and right steered wheel is installed on this rigid axle or the axletree, when single wheel is beated because of road is uneven, beating of this sidecar wheel will influence the work of opposite side wheel, therefore can cause car load and ground-surface adhesion value variation, thus the road-holding property variation when road-holding property is especially run at high speed.In addition, because the connection mode of suspension frame structure and steering structure, glancing impact easily produces deviation phenomenon, and the holder of left and right steel spring simultaneously causes the roll rate of suspension to be restricted apart from less, and the roll stability of automobile is also bad.
Compare with dependent suspension, because independent suspension adopts broken bridge of car, the position of driving engine can reduce and move forward, make the center of gravity of automobile reduce, and reduced the nonspring carried mass of automobile, in the deformation range of suspension elastic element, the both sides wheel can independently moving, be independent of each other, thereby can reduce the vibration of vehicle frame and vehicle body when on rough road, travelling, and help to eliminate the bad phenomenon of the continuous beat of wheel flutter, so the ride comfort of running car, the traveling comfort taken improve greatly, and have improved the stability of automobile operation.Generally speaking, the elastic element of independent suspension only bears vertical load, therefore the main coil spring that adopts, the spring that bears vertical load of air bellow and so on, the spring stiffness of these types limited (being that spring designs softlyer to satisfy cushion characteristic), therefore the weight that can carry is generally less than steel spring, simultaneously, the spring of these types is to the load change sensitivity, less load change tends to make it that bigger elastic deformation amount is taken place, therefore the elastic deformation amount that can take place of the spring of these types is mainly corresponding to the load change of limited amplitude, this makes the application need of independent suspension satisfy a pacing factor, and promptly the rangeability of its load capacity and the load capacity elastic element that need adopt with it adapts.
Rangeability at load capacity and load capacity satisfies under the situation of independent suspension application conditions, because the advantage of independent suspension can remedy the above-mentioned shortcoming of dependent suspension, so the front suspension system of automobile adopts independent suspension to become a kind of development tendency.At present, independent suspension system has been widely used on the forward and backward suspension of car, but, for some automobiles, for example light truck (being that load carrying ability is at the truck below 3 tons), passenger vehicle etc., because its load capacity is big and rangeability load is bigger, so its forward and backward suspension still generally adopts the dependent suspension of forms such as steel spring.This suspension arrangement form especially adopts the dependent suspension of forms such as steel spring with automobile steering roller (being the front axle zone) bonded assembly front suspension, can reduce the stability of the ride comfort of running car, the traveling comfort of taking and automobile operation etc. as mentioned above.In fact, force analysis by routine as can be known, at light truck, on passenger vehicle and so on automobile, though the integrated carrying weight of automobile is bigger, but the distribution of load capacity generally is that preceding light back is heavy, the load that is near automotive front (being the front axle zone) is also little, and the load change amplitude is also smaller, therefore the front suspension of this class automobile possesses the condition that adopts independent suspension fully, promptly adopt independent suspension not only can adapt to the load change amplitude of this class automotive front fully, and can optimize the ride comfort of running car, the traveling comfort of taking and the stationarity of automobile operation etc.That is to say, on the little automobile of the front axle zone of light truck, passenger vehicle and so on load change amplitude, its rear suspension then can adopt independent suspension because need bear the dependent suspension that the load that changes significantly can be selected forms such as steel spring fully on front suspension.
But, problem is: because the weight that the automobile of these types need carry big (for example truck or passenger vehicle are fully loaded) and rigidity of frame is had relatively high expectations, therefore chassis side rail need form the all-in-one-piece straight longeron or the longeron of sinuousness slightly, to improve the loading strength of chassis side rail.The height of this chassis side rail (promptly under the car load installing condition when towards automobile anterior, the top of this longeron cross-sectional plane and bottom diff-H in vertical direction, simultaneously because the height of the longeron of vehicle frame both sides is concordant substantially, therefore this height also can be summarized as the whole height of vehicle frame) generally less, correspondingly, this chassis side rail is also smaller at the height in automobile front axle zone.This longeron does not have problems substantially at the dependent suspension that the steel spring form is installed, and the general deformation space that only needs to guarantee steel spring gets final product.But when independent suspension is installed, because the activity space that independent suspension needs on vertical direction (being the short transverse of chassis side rail) is bigger, to guarantee the deformation space of parts such as coil spring, shock absorber, therefore the chassis side rail of the above-mentioned type also can satisfy the requirement that independent suspension is installed, and promptly can not directly arrange parts such as independent suspension swing arm spare, coil spring, shock absorber.In addition, generally speaking, the integral width of vehicle frame (being the spacing of two side girders of vehicle frame) is subjected to the restriction that automobile entire arrangement, especially chassis whole are arranged, therefore for different automobiles, the integral width of its vehicle frame is determined, thereby the spacing of vehicle frame two side girders and wheel is also determined.Because the installation node at the swing arm part two ends of independent suspension generally is positioned on the support arm of vehicle frame and wheel front axle, if therefore direct mount dependent suspension on above-mentioned vehicle frame, the length of swing arm part is determined substantially.But when arranging independent suspension system, the length of the swing arm part of independent suspension need design accordingly according to turning efficiency, and the integral width of the vehicle frame of the above-mentioned type has but limited the variation of swing arm part length.
The problems referred to above have caused the difficulty of using independent suspension system on the little automobile of the front axle of light truck, passenger vehicle and so on zone load change amplitude, and this also is the major cause that the front suspension system of automobiles such as light truck, passenger vehicle can't extensively adopt independent suspension system.
